Look in the statistics section under the normal distribution and then check out finding an observed value in the exam section, plenty of examples there.

Oh well, hope it turns out ok for you when you get your marks. I have heard that the moments question was difficult from a lot of people.

I really enjoy your work but I am having trouble with a subject you went over previously called normal distribution. I am unsure how you go about calculating exceeding percentages.

For example
The weights of bags of red gravel may be modeled by a normal distribution with a mean of 25.8kg and a standard deviation of 0.5 kg

How would you determined to two decimal places the weight exceeded by 75% of bags?

I have been trying to look for the answer to this type of problem but have failed. :(
